THERMOECONOMIC ANALYSIS OF A CUBAN SUGAR-CANE MILL

Cogeneration is usual practice in sugar-cane mills. In this work, ther moeconomic analysis is applied to the cogeneration system of a typical Cuban sugar-cane mill. Two different cost attribution methods, the ex traction method and the equality method are used to evaluate the exerg etic and monetary (operational) costs of each Aux within the system, e specially the steam and generated power. The methodology indicates the equipment responsible for the greatest irreversibility and for the in crease in the costs of the products of the system. (C) 1998 Elsevier S cience Ltd.
